A Matching Network for a 1.1V Switched Capacitor Power Amplifier has been designed with a Bluetooth Application in mind. The Matching Network has been implemented in a 28nm CMOS RF Metal Stack and provides 16.7dBm output power with IL = 1.1dB at 2.4GHz. A detailed analytical model of power and efficiency of the Matching Network is derived and used for optimal design of the Matching Network. The model shows very good agreement with circuit simulations, and good matching with experimental data as well
